This train has very old rake. atleast the one on which i travelled on 20-12-15. All the Ac coaches were built between 1999-2004. Except B3 which was a '09 built. The condition of the coaches are somewhat average inside and outside. Cleanliness is average. House keeping staff try to clean but passengers make them dirty within minutes. The toilet conditions are PATHETIC. specially the end which is attached to S13. all sleeper class passengers use this washroom and these two are very dirty. Cleaned only once in the morning in BSP. Thats it. Nothing else spotted. I was in B1 63 & 64. Availability of water is good.
